Crown IT4x3500-HD (Speakon) Four channel tour sound amplifier with BSS OmniDrive HD processing


Inside and out, the I-Tech HD is one of the most technologically advanced professional touring amplifiers on the market today. Building on the decades of innovation, invention, and insight Crown is known for, the I-Tech HD features five new patents – three on the power supply alone – giving you an amp that goes well beyond the expected.  


At the heart of the new I-Tech HD is the BSS OMNIDRIVEHD™ processing engine. Four times faster than its predecessor and featuring Linear Phase FIR filters and LevelMAX™ limiters, OMNIDRIVEHD provides unmatched clarity and sonically pure signal processing.


Key Features


  • True Power Density - Crown amplifiers run louder, longer, and with higher fidelity than competing amplifier designs. The I-Tech 4x3500HD is no exception, with four channels of patented Class-I technology packed into a compact 2U design.

  • DriveCore - A culmination of nearly two decades of R&D in PWM and switch-mode amplification, DriveCore™ is a Crown exclusive that combines hundreds of parts into one chip the size of a your fingertip, resulting in more efficiencies and unsurpassed reliability.

  • 4 In/4 Out - each amplifier is capable of independently driving up to four separate zones with a full suite of processing options on each channel.

  • OmniDrive HD - the latest programmable studio-grade 32-bit Sharc® processors with enhanced SIMD architecture and a proprietary D/A output filter for improved signal-to-noise at least 6 dB quieter than outboard DSP

  • Universal power supply with Power Factor Conversion technology

  • Greater than 90% efficiency at full power

  • Five year, no fault, fully transferable warranty
